Objective: To investigate the value of low-dose multi-slice CT (MSCT) chest scan in the diagnosis of coal workers' pneumoconiosis. Methods: A total of 90 patients with a confirmed diagnosis of coal workers' pneumoconiosis were enrolled, and under the conditions of fixed tube voltage, pitch, and slice thickness, they underwent CT scan with a normal dose (150 mA) and a low dose (30-50 mA). The quality of images obtained from two scans was compared, and the imaging findings, opacity profusion, stage, and radiation doses were also compared...

BACKGROUND: Exposure to respirable crystalline silica (RCS) causes emphysema, airflow limitation and chronic obstructive pulmonary disease (COPD). Slate miners are exposed to slate dust containing RCS but their COPD risk has not previously been studied. AIMS: To study the cumulative effect of mining on lung function and risk of COPD in a cohort of Welsh slate miners and whether these were independent of smoking and pneumoconiosis. METHODS: The study was based on a secondary analysis of Medical Research Council (MRC) survey data...

Carbon nanotubes (CNTs) are newly developed materials with unique properties and a range of industrial and commercial applications. A rapid expansion in the production of CNT materials may increase the risk of human exposure to CNTs. Studies in rodents have shown that certain forms of CNTs are potent fibrogenic inducers in the lungs to cause interstitial, bronchial, and pleural fibrosis characterized by the excessive deposition of collagen fibers and the scarring of involved tissues. The cellular and molecular basis underlying the fibrotic response to CNT exposure remains poorly understood...

In 1974, the National Institute for Occupational Safety and Health recommended a ban on the use of silica sand abrasives containing >1% silica due to the risk of silicosis. This gave rise to substitutes including coal slag. An Occupational Safety and Health Administration investigation in 2010 uncovered a case cluster of suspected pneumoconiosis in four former workers at a coal slag processing facility in Illinois, possibly attributable to occupational exposure to coal slag dust. This article presents the results from a National Institute for Occupational Safety and Health industrial hygiene survey at the same coal slag processing facility and a second facility...

AIM: Pneumoconiosis is caused by inhaling dust. The aim of the study was to analyze 208 cases of workers' pneumoconiosis. METHOD: Patients' files were used for the descriptive study. RESULTS: All patients were male aged 38.82±13 years. The most important symptom was breathlessness. Patients were denim sandblasters (50.5%), dental technicians (12%), coal miners (6.7%), and others. The mean exposure time before pneumoconiosis occurred was shorter in denim sandblasters and teflon kitchenware producers compared to other occupations (5...

Occupational lung diseases span a variety of pulmonary disorders caused by inhalation of dusts or chemical antigens in a vocational setting. Included in these are the classic mineral pneumoconioses of silicosis, coal worker's pneumoconiosis, and asbestos-related diseases as well as many immune-mediated and airway-centric diseases, and new and emerging disorders. Although some of these have characteristic imaging appearances, a multidisciplinary approach with focus on occupational exposure history is essential to proper diagnosis...

BACKGROUND: Mining of gold, taconite, and talc may involve exposure to elongate mineral particles (EMP). The involved EMPs are typically non-asbestiform, include dimensions that regulatory definitions exclude, and have been less studied. METHODS: A review of the literature was undertaken for this exposure and occupational epidemiological studies that occur in gold, talc, and taconite mining. RESULTS: Quantitative EMP exposure information in these industries is incomplete...

Objective: To explore the influence of heat shock protein 70 (HSP70) gene genetic susceptibility of coal worker's pneumoconiosis among the han nationality in xinjiang. Methods: 156 coal worker's pneumoconiosis patients and 96 mine workers were randomly selected from the han coal worker's pneumoconiosis patients and attend the health check retirement mine workers from March to December, 2014 in Xinjiang Uygur Autonomous Region of Occupational Disease Hospital.

Objective: To inquiry the changes of serum miRNAs expression in pneumoconiosis complicated with pulmonary tuberculosis patients. Methods: The study subjects (all subjects are male) were divided into three groups: Ⅰstage pneumoconiosis (38 cases) 、Pneumoconiosis complicated with pulmonary tuberculosis (12 cases) and healthy control (40cases) . The first two groups come from Tianjin worker's sanatorium and healthy control group came from a Hospital Health Screening Center.

The H19 is a kind of long noncoding RNA, which has been implicated in multiple biological functions. However, the associations between genetic variants in H19 and susceptibility of coal workers' pneumoconiosis (CWP) have been seldom reported. In the present study, three potential polymorphisms (rs2067051, rs217727, and rs2839702) in H19 were genotyped in a case-control study including 703 CWP cases and 705 controls. We found that individuals with the H19 rs2067051 CT/TT genotypes showed a decreased risk of CWP compared with those with the CC genotype (adjusted OR = 0...

BACKGROUND: Pneumoconiosis is one of the most common occupational diseases, which shows the progressive and irreversible pathological changes. It ultimately can induce pulmonary failure and lead to death. To date, these patients have no curative treatment option under the current standard of care, so it is especially important to delay the onset of the disease and slow down its progression. Therefore, understanding of clinical features of pneumoconiosis is particularly critical for medical intervention...
